Thomcord Grape Vine

The Thomcord Grapevine is a seedless hybrid variety that blends the rich, aromatic flavor of Concord grapes with the mild sweetness of Thompson Seedless. Developed by the USDA's Agricultural Research Service in 1983 and released in 2003, Thomcord has become a favorite among grape enthusiasts for its exceptional taste and adaptability. 

Key Features:

• Flavor Profile: Offers a delightful balance of the classic "labrusca" flavor reminiscent of Concord grapes, mellowed by the sweet, mild notes from its Thompson Seedless parentage.
  

• Berry Characteristics: Medium-sized, blue-black berries with a medium-thick skin that adheres to the flesh, providing a pleasant texture without the slip-skin characteristic of Concord grapes.
  

• Cluster Formation: Produces large clusters that are well-filled yet not overly tight, facilitating ease of harvesting and reducing susceptibility to certain fungal diseases.
  
  

Growing Information:

• Hardiness: Withstands temperatures down to approximately -15°F, making it suitable for USDA Zones 5-9.
  

• Ripening Period: Mid-season ripening, typically maturing between late July and mid-August, allowing for a timely and abundant harvest.
  

• Support: Exhibits moderate vigor, making it adaptable to various training systems and suitable for both commercial vineyards and backyard gardens.
  
  

Cultivation Tips:

• Soil Requirements: Thrives in well-drained, fertile soils with a pH between 5.5 and 6.5. Incorporating organic matter can enhance soil structure and nutrient availability.
  

• Sunlight: Requires full sun exposure, receiving at least 6-8 hours of direct sunlight daily to ensure optimal fruit development and sugar accumulation.
  

• Watering: Maintain consistent soil moisture, especially during dry spells. However, avoid waterlogging, as excessive moisture can lead to root diseases.
  

• Pruning: Implement annual pruning during dormancy to promote healthy growth and maximize fruit production. Focus on removing weak or overcrowded canes to improve air circulation and sunlight penetration.
  
  

Pest and Disease Management:

Thomcord exhibits above-average disease resistance, particularly to powdery mildew, reducing the need for chemical interventions. Regular monitoring and the application of integrated pest management (IPM) strategies are recommended to maintain vine health.

Pollination:

This variety is self-pollinating, eliminating the need for multiple plants for a fruit set. However, planting additional grapevine varieties nearby can enhance cross-pollination, potentially improving yield and fruit quality.
